How to get player steam id?

No a Steam ID is unique / steam account and it will not change. To identify a player use: FUniqueNetIdRepl / FUniqueNetIdSteam. So the UniqueId will give you the SteamID.
I think it has a ToString method according to the code it returns a 64bit integer in an FString. Convert it back to uint64_t then you can use it for database queries.

Thank you Azarus. One question. It’s possible to expose FUniqueNetIdSteam on blueprints? Maybe with a subclass of PlayerState?
